Ssi heat exchanger bottom mounting points
 

What’s the best procedure for attaching heat exchangers to an SC. One hole where the mounting tab goes had a tiny shallow set screw maybe 6mm and not too deep. Are you guys drilling these out larger and tapping or using as is or ??? Thanks.http://forums.pelicanparts.com/uploa...1735663704.jpg

Guess I don’t need them seems like they wouldn’t do much anyway.

The studs for the tabs were originally 6mm .
